Medical therapies for heavy menstrual bleeding in women with uterine fibroids: a retrospective analysis of a large commercially insured population in the USA USA

摘要

Objectives To report patterns and patient characteristics associated with initiation of and persistence with medical therapies for uterine fibroid‐related heavy menstrual bleeding. Design Retrospective cohort study. Setting US commercial insurance claims database. Population 41?561 women aged 18–54?years with uterine fibroids and heavy menstrual bleeding who initiated medical therapies from January 2000 through December 2013. Method Multinomial logistic regression was used to assess patient characteristics associated with initiation and persistence. Cox proportional hazards regression was used on propensity score‐matched cohorts to examine change from index medication. Main outcomes measures Initiation of and persistence with four first‐line medical therapies: short‐ and long‐acting reversible contraceptive steroids, leuprolide acetate, and tranexamic acid. Results Most women (79.4%) took short‐acting reversible contraceptive steroids as first‐line therapy ( index medication ), whereas 9.5%, 8.5%, and 2.7% used long‐acting reversible contraceptive steroids, leuprolide acetate, and tranexamic acid, respectively. During follow‐up, 16?594 women (39.9%) switched to nonindex medication (18.4%) or procedural treatment (81.6%). In comparison with women taking short‐acting steroids, those receiving long‐acting steroids were less likely to switch [hazard ratio ( HR ) 0.84, 95% CI 0.79–0.91], whereas women taking leuprolide acetate ( HR 2.44, 95% CI 2.27–2.62) or tranexamic acid ( HR 1.44, 95% CI 1.26–1.65) were more likely to switch. Older age, emergency department visits, anaemia, and inflammatory disease diagnoses at baseline were associated with increased probability of discontinuing the index medication or switching to another therapy. Conclusions Women with uterine fibroid‐related heavy menstrual bleeding were more likely to persist with their initial therapy of long‐acting reversible contraceptive steroid compared with other medical options. Tweetable Abstract 80% women with fibroid‐related heavy menstrual bleeding use SARC , but LARC users are more persistent.
